Felon

A person who has committed a felony is a felon, and upon conviction of a felony in a court of law is known as a convicted felon or a convict. In the United States, where the felony/misdemeanor distinction is still widely applied, the federal government defines a felony as a crime punishable by death or imprisonment in excess of one year. If punishable by exactly one year or less, it is classified as a misdemeanor. Note that the actual prison sentence handed out has no effect on this; the decision is based on the maximum sentence possible under law. For example, if a person is sentenced to six months, but the charge can be “up to two years”, it counts as a felony, in spite of the actual time served being well under a year. Individual states may differ in this definition, using other categories as seriousness or context. (source)
